Genomické testování holštýnského skotu na farmě Viničné Šumice
Nekužová, Daniela
This thesis is focused on genomic testing cows, specifically to verity reliability new form of cattle breeding. The evaluation parameter was milk production. In the theoretical part are mentioned information about origin and extension of Holstein breed, milk productivity, and linear type. Mentioned is genomics and its evolution of use in breeding, as well benefits for breeding practice. Presentef are the basic principeles of breeding in the Czech republic, breeding value estimation principle and calculation of breeding values. Described were principles of genomics breeding value and its two methods of evaluation. Are indicaded the importance of the reference population, and opinion of czech farmers and cattle breeders. Practical parts are divided in two parts. Determine whether genomics affect actual production of milk and how much. After that separate into the best and the worst cows in breeding. Finding the difference of milk production between the origin breeding value and genomics breeding value.

A PROPOSAL OF THE SYSTEM OF INFORMATION FOR BREEDERS OF WARM-BLOOD HORSES
HAVLOVÁ, Lucie
The aim of this work was to compile a summary of the information provided to the public breeders by the five warm-blood horse breeding organizations in the Czech Republic. Mentioned horses are used for sporting purposes. A similar report was done on the extent and quality of information provided to the public breeders in neighboring European countries. We had prepared a proposal for a system that would provide the necessary information for effective breeding work . In the Czech Republic there is a system for collecting information about the population of horses. However, it is necessary to evaluate and publish information in an understandable form to breeders. As a basis for the preparation of tabular overview of the number of warm-blood horses bred in the Czech Republic, were collected the data from the Central horse register website and data from yearbooks and websites of individual breeders associations. Data were collected for the period of 2006 - 2013. In this thesis the processed data covers these breeds: Czech warmblood, Slovak warmblood, Moravian warmblood , Kinsky horse and Czech Traken. We have suggested the system, configuration and method for disclosure of the breeding information for warm-blood horse breeders and there is also recommended the annual frequency. As a model stallion was chosen Dutch warmblood Great Pleasure and we have created an information portfolio of this stallion. The system of the published information includes identification of the horse, pedigree, exterior evaluation, the results of his performance, comparing features and characteristics of the offspring population and the average breeding value estimation for exterior and performance. An important point is to make the overview of births and evaluated offspring. The proposed system should allow the improvement of the current breeding process and provide objective information to breeders for the right breeding decisions.

Influence of selected factors on the fattening capacity and carcass values of bulls in the control station Želeč
PUFR, Josef
Cattle breeding is one of the part of traditional Czech agriculture. It is a vital part of economy consisting of two main branches - milk and beef production. Beef is one of the main products of cattle breeding sometimes provided by fattening of heifers, cows and bulls. Producing meat with the highest quality with low costs is the main goal of fattening the cattles. I have tested the influence of selected fators on the fattening capacity and carcass values of Czech Fleckvieh bulls in the control station as well as the economic requirements of the fattening period. I have compared the test period of 530 ? 10 days with period of 610 ? 10 days of fattening using the old and new technology of supplementation. Further fattening was provided by results of growing Charolais, Limousin and Czech Fleckvies x Simmental bulls. The results suggest that the increase of the period of fattening for 80 days had a positive effect on carcass yield (p < 0.001), assigning in the classification according to SEUROP and profitability of farming. The positiv relationships between breeding value of fathers and carcass yield of their sons was observed. Finally, the positive influence of new technology of fattening on the classification acording to SEUROP was shown.

Influence of chosen effects on efficiency of beef breeds
WITZANY, Jiří
Influence of chosen effects on efficiency of beef breeds Aberdeen Angus, Charolais, Limousine and meat-type Siemental, which were breeded in South Bohemia, was observed in this study. Impact of breed on average weight of calves in different ages, calving month and the serial number of the birth, influence of father´s relative breeding value, dependence of average age of pure bred female on reason of elimination and effect of stocking rate of a pasture on daily weight gain were evaluated.
